First url is intel macOS support, second is gate for service worker support. Couldn't find one for Linux support.

We discussed this in today's BCD meeting, and it's a bit tricky:
- The DOM interfaces seem to actually be available on all platforms, even if
requestAdapter()will not return an adapter.- The notes currently don't explain what "unsupported" means.
@caugner Thank you. Here is some proposed text then. If you are OK with this I'll roll it out everywhere. If not, can you please counter-propose some text?

FF147 supports WebGPU on on all macOS versions on apple silicon in https://bugzilla.mozilla.org/show_bug.cgi?id=1993341.
Previously it was only supported on Tahoe - I can't find a bug for that, but this issue stated that it was added for Tahoe in 145. It isn't supported on Linux. It isn't supported on macOS on Intel.
I have updated the (partial) subfeatures in the 250+ places that support is recorded.
